Taipei, April 28 (CNA) Police began to disperse hundreds of the protesters who have occupied a main traffic artery in front of the Taipei Rail Station since Sunday afternoon with water cannons. Police took the action at around 3 a.m. after failed attempts earlier to persuade the protesters to leave the Zhongxiao Wast Road. Sporadic scuffles erupted when police tried to remove the protesters with hands. Thousands of people took to the street Sunday afternoon to ask the government to immediately stop the construction of the fourth nuclear power plant and to lower the voter turnout threshold for holding a national referendum to decide the fate of the power located in New Taipei City. Although a spokesman of the ruling Kuomintang (KMT) announced late Sunday afternoon that government has agreed to halt the construction work of the controversial plant, part of the demonstrators refused to leave, saying they will continue their occupation until a government announcement is available instead of the KMT one. Taipei Mayor Hau lung-bin vowed later Sunday night to use all means to return traffic in Zohngxiao West Road to normal by Monday morning as the occupation had seriously impacted traffic in downtown Taipei.
